Problem retrieving datetime

I have a problem retrieving the dates in my Rest API.

I insert a data and the datetime is automatically filled in my BD. for example.

2017-09-27T23:16:46.000Z this value that is generated automatically and I can see it with mysql workbench.

But when I recover with my API it is a basic query like this:

select * from inv;

Returns 2017-09-27T21:16:46.000Z with two hours less than the value of the database.

What could be the problem?

I insert two images so that you can see the table and the response of the API.

Greetings and thanks.

EDIT:

This is the code I use to launch the request to the DB:

    function getInvTop(req, res) {

        if (connection)
        {

            connection.query('SELECT * FROM invjuan WHERE attrName = "sensor2" ORDER BY recvTime DESC LIMIT 15', function(err, rows) {
                if(err)
                {
                    throw err;
                    console.log('Error al Conectar' + error);
                }
                else
                {
                    res.status(200).json(rows);
                }
            });
        }
    }

For the answer for now I only call the method from Postman.

As a client I am using Angular4 , I do not know if the correct thing is to format the date from this one.

If I launch this query it gives me the following error:

SELECT recvTimeTs, CONVERT_TZ('recvTime','GMT','MET'), fiwareServicePath, entityId, entityType, attrName, attrType, attrValue, attrMd FROM iof.invjuan WHERE attrName = "sensor2" ORDER BY recvTime DESC LIMIT 15;
